HEEL-STIFFENER MACHINE.

SPECIFICATION forming part of Letters Patent No. 447,944, dated March10, 1891.

Application filed October 2'7, 1890. Serial No. 369.423. (No model.) i

T0 at whom it may concern:

Be it known that I, LOUIS COTE, of St. Hyacinthe, in the Province ofQuebec and Dominion of Canada, have invented certain new and usefulImprovements in Heel-stiffener Machines, of which the following, takenin connection with the accompanying drawings, is a specification.

My invention relates to machines for forming heel-stifieners, and is animprovement upon the machine described in Letters Patent No. 435,481,granted to me September 2, 1890; and it consists of certain novelfeatures of construction, arrangement, and combination of parts, whichwill be readily understood by reference to the description of thedrawings, and to the claims hereinafter given, and in which my inventionis clearly pointed out.

Figure 1 of the drawings is a front elevation of so much of a machine asis necessary Fig. 2 is a side elevation of the same. Fig. 3 is a plan ofthe mechanism for reshaping the side portions of the stiffener andturning the flange on said stiffener. Fig. 4 is a front elevation of aportion of the same parts. Fig. 5 is a vertical section on line 1 l onFig. 3. Fig. 6 is a sectional plan of same parts with the two parts ofthe divided former in contact for the greater part of their lengths, thecutting-plane being on line 2 2 on Figs. 4 and 5. Fig.7 is a simi-' larsectional plan with the free ends of the divided former separated andpressing the side portions of the stifiener between it and the molds,and the reciprocating notched plate moved into the position to turn therear portion of the flange. Figs. 8 and 9 are respectively a sideelevation and an inverted plan of the divided former. Fig. 10'is anelevation of the inner or working face of one of the molds whichco-operate with the divided former to reshape the sides of thecounterstiffener, and Fig. 11 is a central vertical section of thenotched plate for turning the rear portion of the flange. In thedrawings, Ais the frame of the head of the machine, constructed andarranged to be supported upon a column B, only a small portion of theupper end of which is shown, said frame having mounted in suitablebearings formed thereon the horizontal shafts G, D, E, and F. 4

G and G are the tight and loose pulleys on the driving-shaft O.

a, b, c, and m are gear-wheels connecting said shafts.

g and g are fluted rolls for corrugating that portion of the blank fromwhich the flange or heel-seat of the stiffener is to be formed.

H and H are respectively the former and mold for performing the secondoperation upon the blank of imparting thereto curves both longitudinallyand transversely. I and J are respectively a revoluble disk and anadjustable mold for performing the third operation, or the reshaping ofthe center or rear portion of the partially-formed or clam-shellcounter-stiifener.-

So far the several parts of the machine are constructed, arranged, andoperated substantially as in my before-cited patent.

In the machine described in my beforecited patent the table L wassecurely bolted to the frame A and had formed in its upper surface atransverse groove, in which were fitted two sliding plates, upon whichwere pivoted two molds to co-operate with a divided former pivoted tothe table L, to reshape the side portions of the stiffener withoutattempting to turn the flange.

In my present invention I form the molds O 0 with'theinwardly-projecting lips e a, which extend along those portions of theirlengths which act upon the side portions of the partially-formed counterto reshape the same, said lips 6 extending under the two parts of thedivided former P, each of which is provided with the lip or rib f,extending along its bottom surface, saidribs f'being of a verticalheight equal to the width of the flange to be turned on thecounter-stiffener and serve to raise the main body of the former abovethe surface of the table a sufficient distance to permit the lips e ofthe molds O to pass beneath the body of said former, carrying therewiththose portions of the blank which are to form the flanges of the sidesof the counter-stiffener.

The two parts of the former P are pivoted together and to the table L,and the molds O O are pivoted to the sliding plates M in sub. stantiallythe same manner as in my beforecited prior patent.

In my prior patent the slides M were face of said table into the saidbore to receive said slides, as shown. The outer ends of said bore areclosed by the screw-plugs N N, and between the inner ends of said plugsand the outer ends of the pistons N N are placed circular disks of'thickrubber Q, which serve as springs to press said pistons, their attachedslides, and the molds O Otoward each other.

The ribs fon the under side of the two parts of the former P extendtoward the heel end of the former only to the outer side of the pivotalpin about which said parts move, so that the rear portion of the loweredge of the counter may be turned under said former to form the flangeor heel-seat around the heel end of the counter-stifiener.

The front end of the table L has formed therein the open slot h, inwhich is fitted, so as to be movable toward and from the front of saidtable therein, the block or arm R, upon the upper end of which is firmlysecured the plate S, the inner edge of which has formed therein thecurved notchz'and recess j, fitted to conform substantially to the underside of that portion of the former under which the blank is to be turnedto form a flange around the heel end of the stiffener.

The lower end of the arm R is fitted upon the rod T by a sliding fit andis arranged to be locked to said rod by means of the latch-lever 7c,pivoted to said arm at 7t and arranged to engage with the notch Z,formed in said rod T, at the pleasure of the operator. This isaccomplished by means of the link or rod m, pivoted at its upper end tothe free or movable end of the latch-lever is and at its lower end to atreadle,(notshown,) said latch-lever, rod, and treadle being raised todisengage said latch-lever from the notch Z by the spring 02, all asshown in Figs. 1 and 2.

The rod T has formed in one piece therewith the yoke T, in which isformed the slot 0, extending at right angles to the axis of said bar,with which slot the crank-pin 19, set in the disk U, operates to impartto-said rod a reciprocating motion at each revolution of the shaftV,upon which the disk U is mounted.

The shaft V is mounted in suitable bearings in the frame A and hassecured thereon the spur gear-wheel WV, the teeth of which engage withand are act-ed upon by the teeth of the gear on to impart to said shaftV a rotary motion.

X is the cam for moving the free ends of the two parts of the dividedformeraway from each other, and Y is the spring for moving said partstoward each other and toward the cam, arranged to operate substantiallyas in my prior patent before cited.

The operation of my improvement is as follows: The parts being in thepositions shown in Figs. 1, 2, and 3 and the driving-belt being shippedupon the tight pulley, so as to set the machine in motion, the blank issubjected to the first three operations by passing it endwise betweenthe fluted rolls g then between the former H and mold H and thentransversely between the edge of the disk I and the mold J to reshapethe center or heel portion of the partially-formed counter-stiffener.The counter-stiffener is then slipped endwise upon the heel end of theformer with its sides between said former and the molds O and its baseedge resting on the table and its heel end between said former and theflange-turning plate S, where it is held until its sides have beensubjected to a suitable number of blows in succession to properlyreshape the upright portions of the sides and turn under said former theside portions of the flange or heel-seat, and then the latch-lever 7c ispressed down so as to engage with the notch Z of the rod T, when theplate S will be moved forward beneath the heel end of the former and thefront ends of the molds O, as shown in Fig. 7, thus turning the flangeof the heel and of the counterstiffener and completing the shaping ofthe same. By the use of myinvent-ion counter-stiffeners of any style orsize can be made upon a single machine and have their flanges turned sothat they are ready for use in boots or shoes and require very littlecare or labor of the operator in applying them.

I claim 1. In a machine for shaping counter-stiffeners for boots orshoes, the combination of a former approximating to the shape of theheel portion of a last and provided along the center of itstread-surface with a downwardlyprojecting rib, leaving a recess on eachside, a pair of molds having their inner faces made to conform to theshape of the sides of said former and each provided with a lip tooverlap or pass beneath a portion of the treadsurface of said former,arranged one upon each side of said former and to be moved toward andfrom each other and said former, and a notched plate constructed andarranged to be reciprocated in the direction of the length of saidformer to turn the rear or heel portion of the flange of the stiffener,While the side portions of said flange are turned by the lips on themolds.

2. In a machine for shaping counter-stiffeners for boots or shoes, thecombination of a former made in two parts pivoted together and to thetable or bed of the machine at or near the center of the heel end andprovided with a downwardly-projecting rib extending from its pivotalconnection toward its free or movable end, a pair of molds arranged oneupon each side of said former and mounted upon movable pivots, withtheir inner faces made to conform to the forward side portions of saidformer and each provided with a lip to project under the tread-surfaceof said former to turn the side portions of the flange of the stilfener,springs for pressing said molds toward the former, a reciprocatingnotched plate for turning the rear portion of the flange of thestiffener, a revolving wedge-like cam constructed and arranged toactupon the free or movable ends of the two parts of said former toseparate them, and a spring to move said part-s toward each other andsaid cam.
